Operating instructions
1 Safety instructions
Electrical equipment may only be installed and fitted by electrically skilled persons.
Failure to observe the instructions may cause damage to the device and result in fire and
other hazards.
Danger of electric shock. Always disconnect before carrying out work on the devise or
load. At the same time, take into account all circuit breakers that supply dangerous
voltage to the device or load.
Danger of electric shock. Device is not suitable for disconnection from supply voltage.
The load is not electrically isolated from the mains even when the device is switched off.
Do not connect any electronic lamps, e.g. switchable or dimmable compact fluorescent
lamps or LED lamps. Device can be damaged.
Fire hazard. For operation with inductive transformers, each transformer must be fused
on the primary side in accordance with the manufacturer's instructions. Only safety
transformers according to EN 61558-2-6 may be used.
The radio communication takes place via a non-exclusively available transmission path,
and is therefore not suitable for safety-related applications, such as emergency stop and
emergency call.
Danger of electric shock. The antenna has basic insulation. Do not lead it through the
appliance box.
Do not shorten, extend or strip the antenna. Device can be damaged.
These instructions are an integral part of the product, and must remain with the end
customer.

System information
By statute, the reception characteristics and the antenna cannot be changed.
The device may be operated in all EU and EFTA countries.
The declaration of conformity can be viewed on our website.
The range of a radio system from the transmitter to the receiver depends on various
circumstances.
The range of the system can be optimised by selecting the optimal installation location, taking
into account the structural circumstances.

i Flickering of the connected lamps due to undershoot of the specified minimum load or
through centralised pulses from the power stations. These are not device faults.
i Brief flickering upon load detection of ohmic loads. No operation is possible during load
detection.
4 Operation
A radio transmitter has to be taught in order to be able to operate the dimmer.
i Observe the instructions for the radio transmitter.
5 Information for electrically skilled persons
5.1 Fitting and electrical connection
DANGER!
Electrical shock when live parts are touched.
Electrical shocks can be fatal.
Before carrying out work on the device or load, disengage all the
corresponding circuit breakers. Cover up live parts in the working environment.
Connecting and mounting the dimmer
Maintain a distance of at least 0.5 m from metal surfaces and electrical devices, e.g. microwave
ovens, hi-fi and TV systems, electronic ballasts or transformers.
Maintain a distance of at least 1 m between transmitter and receiver in order to prevent
overmodulation of the receiver.

o Connect the dimmer (1) to lamp terminals according to connection diagram (figure 3) (see
Using the lamp terminals).
Figure 4
o Insert the dimmer in the appliance box in such a way that the programming button and the
LED are visible.
o Lay the antenna (4) stretched out freely if possible (figure 4).
o Switch on mains voltage.
The dimmer automatically sets the dimming principle suitable for the load.
i The load can be switched on or off by pressing the programming button briefly (for about
1 second).

cable (figure 6).
Figure 7: Connection of the single-stranded cable
o Push the single-stranded cable into the round opening on the installation side up to the
stop (figure 7).
5.2 Commissioning
i Observe the instructions for the radio transmitter.
DANGER!
Electrical shock when live parts are touched.
Electrical shocks can be fatal.
Before working on the device, cover up live parts in the working environment.
Teaching a radio transmitter
i If all memory slots are occupied, a radio transmitter which has already been taught must
first be deleted. To do this, delete all taught channels and light scenes of the radio
transmitter individually.
The distance between the receiver and the radio transmitter is from 0.5 m to 5 m.
Load is switched off.
o Press the programming button for approx. 4 seconds.
The LED blinks. The device is in programming mode for approx. 1 minute.
o Trigger teach telegram on radio transmitter (see instructions for radio transmitter).

The symbols used to label the dimmer load shows the load type that can be
connected to a dimmer and the electric behaviour of a load:
R = ohmic, L = inductive, C = capacitive
6.2 Troubleshooting
The dimmer switches the load off briefly and then on again.
Cause: short-circuit protection has tripped but now there is no longer a fault.
The dimmer switches the load off and cannot be switched on again.
Cause 1: electronic short-circuit protection has tripped.
Eliminate short-circuit.
i The electronic short-circuit protection is not based on a conventional fuse, no electrical
isolation of the load circuit.
Cause 2: overheating protection has tripped.
Disconnect dimmer from mains, also switch associated off circuit breakers.
Let dimmer cool down for at least 15 minutes.
Check the installation situation.
Reduce the connected load.
Switch circuit breakers and dimmer on again.
Dimmer does not respond, or only sometimes.
Cause 1: battery in the transmitter is empty.
Change the battery.
Cause 2: radio range has been exceeded. Structural obstacles reduce the range.
Check the installation situation.
Check routing of antenna. Laying the antenna stretched out increases the range.
Using a radio repeater.
